The familiar smell of a fried voice coil

After spending much of last night adjusting the gain on my amp and getting it right (so I thought), I was cruising to work and got that sense that something wasn't quite right. I could smell the burnt electrical scent coming from my trunk. I opened my trunk and yes it was there, so I'm sure at least one of my comp vr's is toast. That makes it 2 speakers in the last 2 weeks since my PPI amp shorted out and my rainbow woofer went kaput. I love this hobby :)

I will test them when I get home and see if at least one is okay. Anyone have any suggestions for where to get a 2003 model comp vr, or where to get one fixed? I will post whether they are both blown or just one.

im glad im not the only one stuff is breaking on. Im sorry your stuff is breaking though, it sucks. The only smelled the electrical smell is when i hooked up my 2 mtx 10s to my jbl 1200.1 lol

So the JBL was too much power for them? I think my new Arc 1000.2 was a little too much power as well.

what went wrong with the rainbow sub, and are you interested in getting rid of it.

since we're sort of on this topic, are there any tutorials/websites/guides or what ever on setting the gain properly so this doesn't happen (to me :P)...

it was the 61/2 woofer for my component. I am working with alumapro to get another one. That is taking quite a while.

Proper gain setting won't prevent you from frying subs. But to properly set your gain you would need an oscilloscope, which costs ... a lot.

The general rule of thumb when doing it (or how most people do it) is turning your head unit up 75-80% of the maximum volume and play a test tone (or music even) that is clear and clean. With the gain all the way down, turn it up slowly until it is either comfortable for you, or to the point before there is any audible change in the sound reproduced.

Do you think there is any chance the subs are okay if I smelled that burning smell? Please tell me yes :unwell011

You most definately have a chance. Even I've smelled my voice coil burning (when I had my Perfect 12.1 in my van). That sub is rated for 350 rms, I gave it 600 :) . It still plays fine here in my room with me.

Could have been the glue burning a bit. You could still be in luck.
